Neste apêndice são apresentados alguns tempos, em segundos, refletindo a reconfiguração de um agente passivo previamente eleito para atuar como agente ativo. Todos os experimentos foram executados durante 60 s, sendo tempo suficiente para se perceber a reconfiguração do agente passivo. Para ativar o mecanismo de reconfiguração, foi desativado o agente ativo deliberadamente para provocar uma falha no cenário contendo apenas dois nós [ver item 7.2.1]. Os dados das Figuras C.1/2/3 foram filtrados no ethereal para melhor leitura dos dados gerados pelos agentes ativo e passivo [ver apêndice A]. A título de exemplo, tem-se na figura C.1, na linha 67, em ~14,9650 s, um agente ativo (172.1.16.5) que faz Flooding do seu último agent advertisement (realçado em negrito). Na linha 68, o agente passivo (172.1.16.42) responde em ~14,9651s com uma mensagem Mnnodelect_Ack para o agente ativo. Nesse espaço de tempo, tem-se a troca de mensagens de sinalização do protocolo de roteamento AODV para garantir a manutenção da rota ativa entre os dois agentes. Em [3], define-se que um nó MIPv4 tem de esperar por pelo menos 3 agent advertisements consecutivos para decidir se perdeu a sinalização com o agente de mobilidade (neste caso deveria ter acontecido em ~14,9650+3 = ~17, 9650 s). Assim sendo, a reconfiguração ocorre como previsto na linha 77, com o agente (172.1.16.42) sendo o novo ativo na rede.
